General
I enjoyed the game! Super big fan of the story telling in the game! Never played Celeste myself but I could see what you were going for.
Only issue that I had was that the controls sometimes were hard not sure if intended.
Overall not bad at all! If you miss making games I would say start making some free time for (if you have some). I’m sure you will enjoy it!
Bug? I am not sure if this is a bug or not since I have no clue but I could dash upwards if I pressed up and after I jumped and pressed the dash button. Could be intentional.
